Gardeners know how much time and effort is spent on the cultivation of strawberries. It is necessary to water the seedlings in time, trim the antennae, remove weeds from the garden beds and do not forget about feeding. Today there are new technologies that facilitate this hard work. Strawberries under the agrofiber are grown in a simple and affordable way, which is becoming increasingly widespread.
Agrofibre or, in other words, spunbond is a polymer having a fabric web structure and having certain desired properties:
- it perfectly passes air, moisture and sunlight;
- spunbond retains heat, providing optimal microclimate beds or seedlings;
- at the same time protects strawberries from ultraviolet rays;
- agrofibre prevents the growth of weeds in the garden;
- protects strawberry seedlings from mold and slugs;
- eliminates the need for herbicides;
- environmental friendliness of agrofibre and low cost are also attracted.
Agrofibre is of two types. White is used as a shelter for beds after planting strawberries. Spunbond can cover directly the bushes themselves, it will create a greenhouse effect for them. Growing up, seedlings raise light agrofibre. It is possible to lift the spunbond in advance with the help of supporting curved rods. During weeding the bushes can be easily removed, and then lay again. If the density is chosen correctly, then white agrofibre can be kept on the beds from early spring until harvest time.
The purpose of the black spunbond is just the opposite - it has a mulching effect and maintains optimal temperature and humidity in the bed, and for strawberries it is the necessary dryness. Spunbond has other beneficial properties:
- there is no need for frequent watering of the seedlings;
- the bed gets rid of weeds;
- microflora is not dried in the top layer of soil;
- agrofibre prevents the penetration of pests - bear, beetles;
- strawberries remain clean and ripen faster;
- the antennae of strawberry bushes do not become tangled and do not germinate; their reproduction can be regulated by cutting off the excess;
- Agrofibre can be used for several seasons.
Advantages of spunbond over film
Agrofibre has several advantages over plastic film. It retains heat well and can protect seedlings from cold during frosts. Polyethylene has certain disadvantages:
- strawberries under the film are subject to such adverse factors as overheating of the soil, inhibition of microflora;
- during frosts under the film forms a condensate, which leads to its icing;
- it lasts just one season.
It is important to choose the right agrofiber in order to effectively use all its useful properties. As a mulching material for beds, black spunbond with a density of 60 g / sq. Is best. m. It will serve excellent for more than three seasons. The thinnest variety of white agrofibre with a density of 17 g / sq. m will protect strawberries from excessive exposure to sunlight, heavy rain or hail, as well as birds and insects. To protect against severe frosts - up to minus 9 degrees, apply spunbond with a density of from 40 to 60 g / sq. m
Preparation of beds
For planting strawberries on agrofibre, you must first prepare the beds. Since they will be sheltered within three to four years, a thorough work is required.
- First you need to choose a dry area, well lit by the sun, and dig it. Strawberry under the film grows well on slightly acidic medium loamy soils. It gives high yields in the beds, where beans, mustard and peas were planted.
- We must clean the soil from the roots of weeds, stones and other debris.
- Organic and mineral fertilizers should be added to the land, depending on the type of soil and the climatic characteristics of the area. On average, it is recommended to add a bucket of humus with two cups of wood ash and 100 g of nitrogen fertilizers to one square meter of beds. If necessary, you can add sand and mix well or dig again.
- The beds must be carefully loosened and leveled. The soil should be loose and light. If after the rains the ground is wet and sticky, it is better to wait a few days until it dries.
When the beds are ready, you need to properly lay a spunbond on them. To grow strawberries on black film you need to choose the highest density agrofibre. It is sold in rolls with a width of one and a half to four and a length of ten meters. It is necessary to carefully lay the spunbond on the ready-made garden bed and carefully fasten the edges of wind gusts. Stones or cobblestones are suitable for this purpose. Experienced gardeners fix agrofibre using artificial hairpins, cut from wire. They are stabbed with agrofibre, putting small pieces of linoleum on top of it.
If it is required to use several cuts of a spunbond, then it needs to be laid with overlap up to 20 cm, otherwise the joints will diverge, and weeds will grow in the resulting opening of the beds. Agrofibre should fit snugly to the ground, so the rows between rows can be additionally mulched with sawdust, they retain moisture well.Important! For the convenience of processing and picking strawberries should provide a sufficient width of the tracks between the beds.
Selection of seedlings
When selecting seedlings, it is advisable to follow some rules:
- if strawberries are planted in spring, it is better to select young bushes, and in the fall - antennae of this year;
- strawberry stalks and leaves should not be damaged;
- seedlings with burnt roots better reject;
- before planting it is good to hold strawberry bushes in a cool place for several days;
- if strawberry seedlings are grown in cups, it is necessary to dig a hole deeper;
- seedlings grown in open ground, a deep hole is not required, as they are slightly pruned roots;
- Before planting each strawberry bush dipped in a solution of clay with water.
Growing strawberries on agrofibre film has some peculiarities. On the canvas spunbond you need to mark the landing pattern. Chalk marks the cut. The optimal distance between strawberry bushes is 40 cm, and between the rows - 30 cm. In the places marked, neat cuts are made with a sharp knife or scissors approximately 10x10 cm in size, depending on the size of the bush.
The seedlings are planted in the finished holes.Important! Rosette bush must remain on the surface, otherwise it may die.
After planting, each strawberry bush is poured with plenty of water.
Strawberries planted on spunbond do not require constant watering, because they do not like high humidity. Abundant sprinkling require only landing points and dry periods. You can water the seedlings from the watering can directly on the surface of the spunbond. However, the lack of water for strawberries is also harmful, during flowering and ripening, it should be regularly watered about two or three times every week.
The best way is to organize a drip irrigation system:
- water flows directly to the roots of strawberries, leaving the inter-row spaces dry;
- it remains in the bed for a long time, due to slow evaporation;
- fine spraying evenly distributes moisture in the soil;
- after drying, no hard crust is formed;
- watering time of seedlings in the middle zone of the country is about 25 minutes, and in the southern regions is slightly longer;
- during the strawberry harvesting period, it also doubles approximately;
- drip irrigation of beds is carried out only in sunny weather;
- through the drip irrigation system, it is also possible to feed the seedlings with mineral fertilizers dissolved in water.
Watering strawberries on agrofibre shown on video. Hose or tape with holes fit into the beds at a depth of several centimeters, and the planting scheme of the seedlings is calculated according to the placement of holes in the tape. Drip irrigation eliminates the need for hard work on watering the beds with a watering can.
Caring for strawberries grown on agrofibre
It is much easier to care for garden strawberries on a spunbond than for ordinary ones:
- with the arrival of spring, it is necessary to remove the old yellowed leaves on the bushes;
- trim off extra mustaches that are easier to notice on a spunbond;
- cover the bed for the winter with white agrofibre of the required density to protect against frost.
Numerous reviews of Internet users indicate that the use of agrofibres in the cultivation of strawberries is gaining increasing popularity.Marina Lebedeva, 58, Kursk Strawberry has been growing on black agrofibre for three years now. This is sheer pleasure. Only the birds ate it until it covered the beds with white agrofibre. Due to the rapid warming up of the beds, strawberries ripen two weeks ahead of time.
Galina Matveeva, 63, Bryansk Sawdust dug along with the ground, sprinkled with needles on top. In the garden I install a box on which I stretch black agrofibre and fasten well. Strawberry seedlings every two weeks I water the infusion of herbs. Very happy.
The use of spunbond in greenhouse conditions
Using white agrofibre, you can significantly speed up the ripening of early varieties of strawberries. Planting seedlings carried out in the last week of April or in the first decade of May. Above the beds, a series of low wire arcs is set, one meter apart. From above they are covered with agrofibre. One side should be tightly fastened, and the other should be easy to open. At both ends of the greenhouse, the ends of the spunbond are tied into knots and fixed with pegs. Growing strawberries under the agrofiber does not require complex care. It is enough to monitor the temperature inside the greenhouse. It should not be above 25 degrees. Periodically need to air the seedlings, especially if it is sunny weather.
Modern technologies every year more and more facilitate the work of gardeners and gardeners. Using them, today you can get high yields of your favorite berries, including strawberries, without much difficulty.
